DIAL PLANS
When an extension dials a number that is not available on the local snom ONE tele-
phone system, the system must search for a trunk on which to route the call. To do
this, it consults the dial plan. The job of the dial plan is to use pattern and replacement
strings to route calls out different trunks. Since extensions map to dial plans, dial plans
should be set up before extensions; however, if only one dial plan will be used and it
will be the default dial plan, then this is not as important.

Dial Plan
Multiple dial plans can exist on the same domain, but an extension can be mapped to
only one dial plan. Administrators can assign the same dial plan to multiple extensions
or create multiple dial plans and assign them to different users. A “restrictive” dial plan
might be used to handle only local calls for phones in common areas, and an “interna-
tional” dial plan might be used for international calling by executives.
